Java处理EDI解析的测试类

以下是一个简单的Java测试类，用于解析EDI文件：

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.milyn.edi.unedifact.d96a.D96AInterchangeFactory;

import org.milyn.edi.unedifact.d96a.INVOic.INVOicSegmentGroup.INVOicSegmentGroup1.INVOicSegmentGroup1a.INVOicSegmentGroup1a1;

public class EdiParserTest {
    public static void main(String[] args) throws IOException {
        String ediFile = "example.edi"; // EDI文件路径
        BufferedReader reader = new BufferedReader(new FileReader(ediFile));
        String ediContent = "";
        String line;
        while ((line = reader.readLine()) != null) {
            ediContent += line;
        }
        reader.close();

        D96AInterchangeFactory factory = D96AInterchangeFactory.getInstance();
        INVOic invoice = factory.fromUNEdifact(ediContent, INVOic.class);

        // 获取INVOIC头部信息
        INVOicSegmentGroup1 invoiceHeader = invoice.getINVOicSegmentGroup1();

        System.out.println("Header Information:");
        System.out.println("Invoice Number: " + invoiceHeader.getE1004());
        System.out.println("Invoice Date: " + invoiceHeader.getE1373());
        System.out.println("Invoice Currency Code: " + invoiceHeader.getE6345());

        // 获取INVOIC行项目信息
        List<INVOicSegmentGroup> invoiceItems = invoice.getINVOicSegmentGroup();
        System.out.println("Line Item Information:");
        for (INVOicSegmentGroup item : invoiceItems) {
            INVOicSegmentGroup1a itemHeader = item.getINVOicSegmentGroup1().getINVOicSegmentGroup1a();
            INVOicSegmentGroup11 itemDetail = item.getINVOicSegmentGroup11();

            System.out.println("Item Number: " + itemHeader.getE7140());
            System.out.println("Product Code: " + itemDetail.getE7143());
            System.out.println("Product Description: " + itemDetail.getE7008());
            System.out.println("Invoice Quantity: " + itemDetail.getE6063());
            System.out.println("Invoice Unit Price: " + itemDetail.getE6411());
            System.out.println("Invoice Line Total: " + itemDetail.getE5463());
        }
    }
}

这个测试类使用了Milyn EDI库来解析EDI文件。你需要在项目中添加以下Maven依赖：

<dependency>
    <groupId>org.milyn</groupId>
    <artifactId>milyn-edisax-unedifact</artifactId>
    <version>1.7.1</version>
</dependency>
<dependency>
    <groupId>org.milyn</groupId>
    <artifactId>milyn-smooks-core</artifactId>
    <version>1.7.1</version>
</dependency>

请注意，这个测试类仅适用于特定类型的EDI文件。如果你的EDI文件结构不同，你需要根据你自己的情况编写代码。
